HENRY ROSE, DECEASED; BY WILLIAM HENRY ROSE, ADMINISTRATOR, OF GAINS- BOROUGH, ENGLAND.

WRAPPING MACHINE.

Original application filed January 13. 1921, Serial No. 437,025. Divided and this application filed March 10, 1922. Serial No. 542,807.

To all whom it may concern;

Be it known that I, WILLIAM HENRY Rose, a subject of the King of Great Britain, re siding at Albion Works. Gainsborough, in the county of Lincoln, England, am the administrator of the estate of HENRY Rosa, deceased, and the late HENRY Rosn invented new and useful Improvements in Wrapping Machines, of which thefollowing is a specification.

This invention consists in improvements in wrapping machines such as described and illustrated in British Letters Patents Nos. 20183 of 1900 and 6769 of 1905 for wra ping blocks, or slabs, of sweetmeats suc i, for instance, as chocolate, and the object of the present invention is to so modify the folding devices as to render them capable of effecting the wrapping more securely. This application is a division of application Serial No. 437,025 filed January 13, 1921 now Patent No. 1,434,152.

According to this invention improved means are provided whereby the ends of the last horizontal top fold of the wrap-per are engaged, or interlocked, with the end folds, so that the folds are kept in place and the articles are very securely and evenly wrapped in their wrappers.

I will describe, with reference to the accompanying drawing, wrapping machines in accordance with this invention from which its nature and how it can be performed will be understood. Figures 1 and 2 are side views shewing different positions of the mechanism and Figure '8 is a view at right angles to the other figures and with the parts shewn in positions corresponding to Figure 1. Figure 4 shows the article A partially wrapped. Figures 5 and 6 are views at right angles to each other showing the cross-head and its associated parts constituting the improved folding device. The folding device by which the first end folds of the two laterally projecting ends of the wrapper are made, acts to press the said ends onto a concentric plate, or. guard, 91. The said folding device is provided with yielding fingers 68 which Will permit of the said device acting on articles of slightly different sizes. The said yielding fingers 68 are hinged to a cross-head 69 on a rod 70 slidable in a socket 71, mounted on a stud 72, projecting from the frame of the apparatus, the said rod 70 carrying an antifriction roller 73 which is caused, by aspring 7 5 (surrounding the said rod and interposed between the socket 71 and the cross-head 69 secured to Said rod), to bear on a cam 74, secured to the shaft 64, which effects the reciprocationof the said rod at the proper times. The socket 71 is oscillated on the stud 72 by a cam 75, secured to the shaft 48, which actuates, through an antifriction roller 76, an arm 77, formed in one with, 01' secured to, the socket 71, these being in accordance with the aforesaid prior patents; but in accordance with the present invention, there is pivotally mounted on, and reciprocable with, the crosshead 69 a blade 7 8, which, upon the descent of the end-folding devices, acts to fold a projecting portion 79 of the end 57 of thewrapper onto the side of the article as shewn in Figure 4, which portion 79 acts to more securely maintain the wrapper round the bon-bons when the folding is completed. The movable side of each mould which is adjacent to the blade 78, is of less length than the length of the partially wrapped article, .to permit the side portions 7 8 of the said blade to engage with the projecting portion 79, of the wrapper and press the end portions thereof against the side of the article.

What I claim is:-

In wrapping machines of the kind aforesaid, a folding device provided with yielding fingers hinged to a cross-head operated as hereinbefo-re explained, the said crosshead having mounted upon it, and reciprocable with it, a blade which acts to fold a projecting portion of the end of the wrap per onto the side of the article being wrapped; substantially as, and for the purpose, hereinbefore explained.

In testimonywhereof I have signed my name to this specification in the presence of two subscribing witnesses.
